MAGAZINE-FIREARNI.

SPECIFICATION forming part of Letters Patent No. 787,800, dated April 18, 1905.

Application filed June 30, 1903. Serial No. 163.771.

T0 all whom it may concern:

Be it known that LWILLIAM SONNENBERG, a citizen of the United States, residing at Winona, in the county of Winona and State of Minnesota, have invented certain new and useful Improvements in Magazine-Firearms; and I do declare the following to be a full, clear, and exact description of the invention, suoli as will enable others skilled in the art to which it appcrtains to make and use the same.

This invention relates to an improvement in magazine-iirearms, the object of the invention being to construct a mechanism involving a one-movement action and which will permit the loading and discharging of the gun without removal from the shoulder, as well as to provide a mechanism extremely rapid in its action to load and discharge the gun and a mechanism'compact within its casing.

IVith the above and other objects in view the invention resides in the novel construction, combination, and arrangement of parts,- as will be hereinafter more specifically described and then particularly pointed` out in the claims, and in describing the invention in detail reference will be had to the accompanying drawings, forming apart of this specilication, and wherein like numerals of reference will indicate similar parts throughout the several views, in .which- Figure 1 is a longitudinal sectional view through the breech of the gun, showing the c different parts involved in my invention assembled in position. Fig. 2 is aplan View of same, part of the casing being in section and the breech-block removed. Fig. 3 is a crosssection on line a c, Fig. 1 Figs. 4, 5, and 6 are detail views. Fig. 7 is a View of the trigger and carrier about to receive a cartridge from the magazine. Fig. 8 is a view of the trigger and carrier about to discharge a cartridge into the gun-barrel. Fig. 9 is a view of the trigger and carrier, the carrier being in a non-loading position. Fig. 1() is a view of the breech-block and one of the operatingcams, the breech-block being in a firing position. Fig. 11 is a View 'of the trigger and hammer, the hammer about to strike the firing-pin. Fig. 12 is a view of the trigger and hammer, the hammer being in a cocked position. Fig. 13 is a view of the trigger and part of the extracting mechanism. Fig. 14: is a longitudinal vertical section of the carrier. Fig. 15 is a bottom View of the breechblock. Fig. 16 is a longitudinal vertical section thereof. Fig. 17 is an end view of the breech-block within the casing, the casing being in section. Fig. 18 is a reverse view of the trigger and part of the carrier in dotted lines. Fig. 19 is a detail perspective view of the shell-extractor. Fig. 2O is a detail perspective View of the slide-bar.

Referring to thc accompanying drawings, 1 indicates the lock case or receiver constructed to receive the mechanism and provided with a tang 2, adapted to be secured to the stock of the gun, this lock case or receiver being further provided with an oblong opening 3 in the top for the operation of the breech-block and with a slot 4: to receive the hammer. The lock case or receiver is suitably secured to the rear end of the gun-bary ing. .This bushing is also provided with anl openmg to receive the inner end of the magazine-tube 6, located, preferably, underneath the barrel, as in the usual practice, and in which the cartridges are carried and fed by means of a spring-pressed plunger 7, as inthe usual manner.

The breech-block 8 is pivotally hung in the lock case or receiver on a pin 9 and normallythat is, when the gun is not in action-closes the opening 3, the said breech-block having an oscillatory movement in the lock case or receiver.

Referring to Fig. 16, it will be seen that the breech-block is bored throughout its length adjacent to the upper face to receive the ring-pin 10, the bore and pin being of correspondingly dierent diameters and the pin being held normally in the retracted position by means of a spring 11, arranged on the pin between an' annular shoulder thereon and an annular shoulder in the bore of the block. This pin is grooved on its lower face, as at 12, to receive a set-screw 14 to prevent the withdrawal of the tiring-pin and to limit its movement.

The breech-block has a lower hinged web 15, normally held depressed by means of a spring 16 and provided with a curved iange or rib 17, (see Figs. 15 and 16,) so that when an empty shell is ejected from the barrel it will strike against the curved ange or rib, and be thus guided to and ejected through the opening 18 provided therefor in one side of the lock casing or receiver. (See Fig. 17.) The lower face of the breech-block is provided with a'groove conforming to the shape of the ange or rib and receiving the latter as the breech-block is elevated and the web closes on the breech-block.

The lock casing or receiver is in two parts-- the upper part, as heretofore described, and the lower part 19, constructed with a tang 2O for attachment to the stock of the gun. At its forward end this lower part of the lockcase is secured by a screw 21 to the forward end of the upper part. In the forward end of the lower portion of the lock-case is hinged by means of a pin 22 the shell-extractor 23, the particular shape of which is best seen in Fig. 19 of the drawings, being cut away in one side edge to receive the end of the niagazine-tube and at its upper end having a semicircular recess registering with the bore of the barrel. A spring-pressed bolt 24 is mounted in one wall of the lower part of the lock-case and serves as a cushion for the sudden impact of the shell-extractor as the latter is ejecting a shell and forces the extractor back into posi` tion when the ejecting power is released.

The cartridge-carrier 25 has two rearwardlyextending straps 26, provided near their rear ends with openings to receive the pivot-pin 27, which also serves for the hammer 28. The cartridge-carrier is bored longitudinally to receive the cartridge and a slide-bar 29, which latter has a loop 30 on its rear end to receive the upper end of the trigger, whereby the slide-bar is actuated by and simultaneously with the trigger.

The slide-bar 29 near its forward end is provided with a slot 31, through which is passed a pin, which is also passed through the rear end of a spring loading-plunger 32, to eject the cartridge from the carrier into the barrel, the spring allowing the full stroke of the sliding bar 29 and pressing the cartridge into position. Further backward movement of the plunger is prevented by the pin 31a. The lower edges of the rearwardly extending straps or sides of the cartridge-carrier are formed with a series of cams, as and for the purposes hereinafter set forth.

The trigger 32L has an upwardly-extending portion or end 33, that protrudes into the loop 3() of the slide-bar and carries a roller 34 in its upper end. The said trigger carries pins 35, which engage in slbts 36 in tumblers 37, one at each side of the trigger, and which revolve under the haunches 37 of the breechblock and serve to operate and hold'the latter in place. The trigger carries a pin 38, which when the trigger is operated rearwardly engages the rear end of a locking-pin 39, that is mounted in the Wall of the lower part of the lock-case and forces said pin forwardly against the spring-plunger 39L for the shellextractor, forcing the said plunger back and permitting the ejector to assume the position for the insertion of a cartridge into the barrel. A pin 40, mounted in the lower part of the lock-casing, is engaged by the trigger when the latter is forced forwardly, and this pin operates the sear 40, releasing the locking-pin 39 and allowing the spring-plunger 39 to force the shell-extractor rearwardly to eject the shell. A spring-operated dog 41 is carried by the trigger, which operates upon the cam-surface on the under side of one side of the carrier and is guided in its position by a pin 42. (Shown plainly in Fig. 18.)

A pin 43 extends from one side of the trigger, which engages the cam-surface on the opposite side of the carrier. The trigger also has spurs 44 and 45 and is pivoted by a pin 46, passing through it and extending into the casing at each side. At 46*L is pivoted a short arm 47, engaged by a spring 48, secured to the lower part of the casing.

The sear 40a is pivoted at 49 and at its front end is provided with a tooth 50, which engages a notch 51, Fig. 13, in the under side of the locking-bar 39. The locking-bar is provided at its forward end with a right-angled projection 52, which engages the springplunger 39".

The hammer 28 is provided at its top with a thumb-catch 53, on its forward edge with a spring-lip 54, at its lower extremity with a notchedportion 55, and on its rear edge a cut-out portion 56. It is pivoted on the pin 27 and is spring-held by the springs 57 and 58, which are secured to the lower tang.

The front end of the Sear 40L is pressed upward by a spring 59, seated in a recess in the lower casing. The tumblers 37 are pivoted on short screw-pivots 60, inserted from the outside through the lower casing and into the tumblers.

The spring-plunger 39 is provided with a side extension or lug 63, that engages the extractor 23.

The operation of the mechanism is as follows: Commencing with the position of the several parts when the trigger is in its eX- treme position forward, as shown in Fig. 1, the pin 40 of the sear 40 is flush with the outer surface of the lower casing. In that position dog 41, Fig. 18, rests in a depression 61 of the shell-carrier. A cartridge is shown in the carrier and the barrel-chamber is empty. The first movement backward of the trigger causes dog 41 to raise or lift the shell-carrier on its pivot 27, further movement of the trig- IOO ger continuing lifting carrier until dog 41 reaches the point 62 of the carrier. When the dog reaches this point, the carrier has reached its highest point of *lifting with the cartridge opposite the barrel-chamber ready to be inserted therein. (See Fig. 8.)r The trigger has then moved about one-quarter way back. Continuing the backward movement of the trigger, the spur 45 on the trigger engages the spring-lip 54 on the hammer, Fig. 11, moves the hammer backward, the process of cooking begins immediately, and continues throughout the backward movement of the trigger and until the tripping of the hammer takes place. Still continuing the movement backward of the trigger, the pin or projection 38 on the trigger, Fig. 13, pushes against the bolt 39, the rear end of which bears against said pin or projection, while Athe forward end of the holt rests against the spring bolt or plunger 39, while the projection 63 of the plunger rests against the shell-extractor 23, so that the first movement of the trigger pushes bolt 39 forward, and thereby pushes plunger`39l also forward, at the same time compressing the plunger-spring. Pushing the plunger forward relieves its pressure from the shell-extractor 23 and permits the latter to swing on its hinge or pivot forward. When the pressure of the plunger is withdrawn from the extractor', the spring bolt or pin 24, Fig. 2, forces the extractor into its recess and out of the path of the car-rier. The forward movement of the bolt continues as long as the trigger moves backwardly, moving the plunger 392L forward, so that when Vthe trigger is entirely back and ready to trip the hammer the end of the plunger is some distance ahead of the extractor. After bolt 39 has pushed plunger 39u its full distance the projection or tooth 50 of the sear 40 is forced by the spring 59 into the notch 5l, and thereby locks it in place, preventing the plunger 39 from moving either the bolt or the extractor if the hold on the trigger is released. Still continuing the backward movement of the trigger, the pins 35 on each side of the trigger press against the upper sides of the slots 36 in the tumblers 37, turning said tumblers upon their pivots 60, thereby swinging the upper portions backward. The upper portions move in the circular depressions in the haunches of the breech-block. When the trigger is forward, the tumblers rest as shown in Fig. 1, holding the upper part of the breech-block carrying the firing-pin in place. When the tumblers move toward the rear, as the trigger moves back, the curve in the haunches is so formed as to impart no movement to the upper part of the breech-block. In fact, the tumblers only touch for a short space at the extremity of the curve during their travel from one end to the other. The tumblers reach the rear of the curve when the trigger is almost back and then tip. the forward end the beginning of the backward movement of v the trigger. When the trigger has moved back about one-quarter distance, the shellcarrier is opposite the barrel-chamber. With a further movement backward of the fngerhold of the trigger the upper part moves the loading-plunger 32 forward and pushes the cartridge into the barrel-chamber. this movement takes place, the roller 34 in the up'prlend of the trigger engages the inclined front wall 64 of the loop'30, the purpose of the roller being to cause as little friction as possible and to prevent binding. While loading takes place the hinged part 17 of the breech-block rests against the under side of the upper part, the forward end fitting back of the lip 65,Fig. 10, out of the way yof the carrier, with the top of the carrier resting against the under side thereof. At this point the breechblock is in its highest position. As soon as the loading-plunger has traveled its full length and has deposited the cartridge into the barrel -chamber the tumblers 37 have reached near to the end of the curve of the breechblock, depressing the 'front end thereof, and the front end presses the carrier down. At this point of the operation the dog 41 has reached and rests at a point 66 of the carrier, Fig. 18, the angle being such as to compress the spring 67. The loading rod or plunger being formed in two parts and being springconnected permits the end to slide down without binding during the downward travel of the carrier. As the trigger continues to move back the front end of the breech-block falls, its movement at this time being quite rapid, until opposite the barrel-chamber. When this position is reached. the carrier is a little above its low-est position, opposite the maga- Zine, and supported there by pin 43 a trifle too high to permit a cartridge to leave the magazine, Fig. 9. The trigger has now reached its extreme backward movement and hingelip 54 trips out of engagement with the spur 45 and the hammer is forced forward by the spring 57. The front or head of the hammer strikes the rear end of the firing-pin. The pin strikes the rim of the cartridge and explodes it. suiiicient to relieve the pressure from the firing-pin, permitting the pin to be withdrawn from contact with the shell by the spring 1l. This completes the entire operation by the backward movement of the lower part of the trigger. The forward movement of the trigger is assisted by the spring 48, or, if desired, the spring can be strong enough to bring the trigger back automatically. The movement of the trigger forward causes the tumblers 37 to raise the top of the breechblock, leaving the hinged web down, and the spring 16 assists inholding it down. At this When The spring 58 then rebounds the hammer IOO IIO

time the upper end of the trigger moves the loading rod or plunger backward, preparing the carrier to receive another cartridge from the magazine. No other movement takes place until the trigger strikes the pinion 40 under the sear 40a. The top part of the breechblock is now at its extreme height, with the hinged portion below the barrel-chamber. When the trigger forces the pin 40 upward, it causes the sear to rock and disengage the tooth thereof from the sliding bolt 39, relieving the spring-plunger 39a. The force of the spring drives the bolt back against the pin or `projection on the trigger, and the side projection 63 of the plunger strikes the extractor, forcing it from the barrel-chamber, carrying the empty shell with it, and throws the shell with considerable force against the curved portion of a hinged portion of the breechblock and out of the gun through the opening 18 in the side of the casing. At the same time the pin 43 has changed its position on the bottom of the carrier suiicient to permit the carrier to drop opposite the magazine. To bring the carrier down positively, the spur 44 on the trigger engages the hook 68 on the carrier and pulls the carrier down until the opening in the end of the carrier permits the cartridge to slip into place by force of the magazinespring. During this time the spur 45 has moved over the spring-lip 54 until the spring snaps it into place. This completes the entire operation.

The cartridges in the magazine are held in place by the front face of the carrier. which never moves beyond the opening of the magazine and has a downwardly-extending lip for that purpose.

The hammer can be cocked by hand and held in a cocked position until released by a pressure upon the trigger. When it is cocked by hand, the notch 55 on the hammer engages the spur 45 on the trigger, all other movements being the same whether cocked by hand or trigger.
